Using the pre-provided three.min.js (global THREE), render a full-screen scene with a rotating icosahedron lit by two colored point lights, orbit-style auto-rotation, and a subtle starfield background.

Simple task: write an index.html using three.min.js.

Three.js (probably r12x, UMD build with THREE global). I'll write index.html.

Quick sanity check — verify that IcosahedronGeometry, PointLight, etc. are available in this build. Let me quickly check for "IcosahedronGeometry" within the file. Also, I might verify in node whether the script can parse (syntax).

grep -c counts the number of lines, and since it's minified and all on a single line, having 1 line containing all three is no problem. The APIs being used are standard. Done.
Done. `index.html` is written to `/tmp/ws` — fully self-contained, no network resources. **What it renders:** - **Full-screen scene** — WebGL renderer fills the window, handles resize, caps pixel ratio at 2 - **Icosahedron** — `MeshStandardMaterial` with flat shading plus a subtle white wireframe overlay, spinning on two axes - **Two colored point lights** — a red/pink and a cyan light orbiting the shape on tilted counter-rotating paths, each marked with a small glowing sphere so you can see them circle - **Orbit-style camera** — auto-rotates around the scene; you can also drag (mouse/touch) to orbit manually and scroll to zoom, and auto-rotation resumes on release - **Starfield** — 1,200 `Points` distributed on a distant spherical shell with subtle white/warm/cool tint variation and a very slow drift - Faint ambient light + exponential fog keep dark facets readable without washing out the dark background The JS syntax-checks clean and uses only core APIs (`IcosahedronGeometry`, `PointLight`, `PointsMaterial`, `FogExp2`) that are present in the bundled `three.min.js`.

EVALUATION
Rotating icosahedron with two colored point lights and starfield, continuously animating; keyboard/mouse inputs mostly just reflect rotation over time.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
